Macro partitioning
High protein intake in the first year of life, often resulting from the use of infant formulas when breastfeeding is discouraged, is associated with increased weight gain in children.
If you are not breastfeeding, be aware that infant formulas with high protein content may contribute to faster weight gain in infants. Breastfeeding is associated with a protective effect against later overweight.
ModerateSupportsMEDIUM confidence
There are now consistent data to indicate that a high level of protein intake in the first year of life can lead to weight gain.
Why this rating
Cites consistent data but notes investigation difficulties.

- Genetic susceptibility to obesity, including variants like the FTO gene, can be counteracted by high levels of physical activity.Good
- High levels of physical activity and energy expenditure, such as those derived from cycling as daily transport, act as a protective factor against obesity, although they may be counteracted by high energy-dense diets.Moderate

- Total daily protein intake of 1.6 g/kg/day is sufficient for maximizing resistance training-induced muscle gains, with an upper confidence interval of 2.2 g/kg/day.Strong
- Resistance exercise training combined with sufficient dietary protein intake acts synergistically to maximize skeletal muscle hypertrophy, with protein intake saturating around 1.6 g/kg/day for general populations and potentially requiring 2.0-2.2 g/kg/day for resistance-trained individuals.Strong
- Trans fats should be completely eliminated from the diet, as they increase LDL cholesterol, decrease HDL cholesterol, and are directly associated with increased coronary risk.Strong
